Wireless signal receiving device and method

A wireless signal receiving device capable of making different adjustments for different kinds of wireless communication to configure the wireless signal receiving device adaptively, the wireless signal receiving device comprising:

• a front-end receiving circuit configured to receive a first communication signal through first wireless communication in a first communication duration and then generate a first reception signal according to the first communication signal, the front-end receiving circuit also configured to receive a second communication signal through second wireless communication in a second communication duration and then generate a second reception signal according to the second communication signal, wherein the front-end receiving circuit includes a low noise amplifier, a mixer, a circuit for filtering and analog gain control, an analog-to-digital converter, and a demodulation circuit in sequence;
• and
• a media access control (MAC) and post-processing circuit coupled to the front-end receiving circuit, and configured to adjust at least one first parameter for the first wireless communication according to updated first setting of the first wireless communication and to adjust at least one second parameter for the second wireless communication according to updated second setting of the second wireless communication, wherein the at least one first parameter for the first wireless communication includes a first circuit parameter of the front-end receiving circuit, the at least one second parameter for the second wireless communication includes a second circuit parameter of the front-end receiving circuit, and each of the first circuit parameter and the second circuit parameter is one of the following:
• an amplifier parameter of the low noise amplifier;
• a mixer parameter of the mixer;
• a filter parameter of the circuit for filtering and analog gain control;
• an analog gain control parameter of the circuit for filtering and analog gain control;
• a converter parameter of the analog-to-digital converter;
• and a demodulator parameter of the demodulation circuit,
• wherein the front-end receiving circuit does not receive any signal through the second wireless communication in the first communication duration, and does not receive any signal through the first wireless communication in the second communication duration;
• the first wireless communication is between the wireless signal receiving device and a first wireless device and the second wireless communication is between the wireless signal receiving device and a second wireless device, or each of the first wireless communication and the second wireless communication is between the wireless signal receiving device and one single wireless device while the first wireless communication and the second wireless communication are a first kind of wireless communication and a second kind of wireless communication respectively;
• the updated first setting is determined according to at least one of the first reception signal and first subsidiary information;
• the updated second setting is determined according to at least one of the second reception signal and second subsidiary information;
• the updated first setting is equivalent to or different from the updated second setting;
• the first subsidiary information and the second subsidiary information are dependent on the first wireless communication and the second wireless communication respectively;
• and each of the first subsidiary information and the second subsidiary information includes at least one of the following:
• a signal format for wireless communication;
• master/slave roles for multiple Bluetooth links;
• a usage and interference state with respect to a wireless network;
• remaining battery power;
